The Smok Alien 220 Mod has dimensions of 85mm x 44mm x 28.4mm so it is quite portable for a box mod that puts out a massive 220W . The device is made from zinc alloy with carbon fiber inlays. Its design is very unique with slanted gold or red lines encompassing the larger OLED screen, adjustment buttons and USB port. The screen’s easy-to-read menu features 6 lines and shows wattage, mode, battery level for each cell, resistance, coil type, puff time and number of puffs. At the top of the Alien, there’s a 510 connection and on the side, the over-sized hidden fire button is beautifully integrated into the design.
